A single brief exposure of a photovoltaic (PV) module or coupon to cold temperatures down to -40°C, the lower limit in IEC photovoltaic testing standards, significantly degrades the fracture strength of silicon solar cells. To understand the mechani

Solar panels generally contact the mounting structure only along the surfaces of the aluminum frame surrounding the perimeter of the panel. With no support in the middle of the panel, front side mechanical loads from snow, wind, and human factors can

Existing mechanical durability testing sequences typically perform mechanical loading prior to environmental exposures such as thermal cycling or humidity freeze. Recent work has shown that the fracture strength of silicon solar cells can reduce afte

Electroluminescence (EL) measurements of PV modules with cracked cells have showed some open cracks to close arbitrarily from day to day even though these modules are stored in a controlled, stressor free laboratory environment – constant temperatu

In this work, we performed four variations of cyclic load testing on four groups of modules using the LoadSpot tool. Each group first underwent 50 thermal cycles (TC50), 10 humidity-freeze cycles (HF10), and a 2400 Pa static load. Then, the baseline

Solar cell cracking is a potential reliability concern that may affect the long-term performance of modules that experience mechanical stress in the field. We present a methodology that utilizes EL images to predict power loss due to cell cracking. W

Some crystalline silicon PV system underperformance is due to the presence of cracked solar cells, and this represents a financial risk for both already installed and future systems. This work describes compressive stress strategies and rear side pre

Cracks were created in a PV module by static mechanical loading before installation in the field to quantify the power degradation due to cracks propagating and opening because of cyclic wind loading over a large number of cycles. The magnitude and f

Cell cracking presents a serious risk for the long term reliability of c-Si photovoltaic modules. Cracks may not initially result in performance loss, but over time performance may degrade as the module experiences stresses in the field such as tempe
